Prioritize KPIs and features that drive service and cost:

• Order lead time, pick accuracy, and on‑time shipment rate
• Available storage types (ambient, chilled), racking density and throughput capacity
• Carrier pickup frequency, road access and cross‑dock capabilities
• WMS/API integration and return handling procedures

Carrier access and road quality directly influence transport reliability and unit freight cost. Facilities with regular carrier routes and consolidated daily pickups reduce average transit days and freight premiums. Evaluate pickup windows, linehaul frequency, and multi-carrier options to optimize service levels and cost‑to‑serve.

Key capabilities include robust WMS with real‑time inventory, API or EDI connectivity for order exchange, event‑based tracking (ASN, shipment status), and reporting for cost allocation. Confirm SLA commitments for integration onboarding and data reconciliation to prevent inventory drift and fulfillment delays.

Model total cost‑to‑serve rather than rent alone: include handling fees, inbound/outbound freight, returns processing, and safety stock impacts. Use phased capacity agreements, minimums tied to growth, and performance incentives. Scenario‑based modeling for seasonal peaks clarifies when to add dedicated space vs. flexible 3PL capacity.
